I'm installing the AEM EMS, but having difficulty with trying to see the timing mark with the Vortech installed to calibrate the EMS. How are those of you able to see the timing mark with a timing gun with the Vortech S/C installed?

I found this http://forums.s2ki.com/forums/showthread.p...threadid=121057 but, unfortunately, I still can't seem to get a straight eye on the timing mark. Any advice?

Thanks, Gary

 

Gary, Are you just finding an initial timing mark to set up the EMS? It looks as if you will have to remove the blower from the brackets and run the engine without it to get your initial setting. You could try wiggling and inspection mirror to see if you can get a clear shot, but I think you will still have to pull the blower. I'd try the mirror with the engine off, You don't want to feed the belts a mirror.

 

Yeah, just the initial timing mark. I was hoping to not have to remove the S/C, but it looks that way... I was planning on trying a mirror first, but I don't want to get close to the belts (like you mentioned), so doubt I'll be able to see it with a mirror... Guess it'll be coming off again if not..

My buddy is just about done with injectors, so that's the next step once I get these crude base map calculations done to start the engine.

 

My father had a good idea. If I can use a mirror to line up the 0 degree mark with the indicator. I can then put a mark on the pulley and the block someplace else (i.e. under the car). I'll try it normal with mirrors and a timing light, but if not I'll most likely try this other idea.

 

Sounds like a good plan to me

 

thanks for sharing these info gary
I will follow your modification path *hopefully* shortly

Could you take the intercooler off to do this setting? It will give you some more room and save you the dreaded task of removing the SC

 

The Timing mark is on "blower" side of the timing cover, moving the aftercooler doesn't free up your line of sight. I don't know if the Comptech guys would have the same problem, they mount the blower farther to the center of the engine.

 

I just took off the intercooler, and able to see the timing mark and pulley marks (although it's difficult) enough to mark the front of the engine and pulley with an alternate mark. This should be good, I'll show a picture of what I did afterwards.

FYI, I also tried with a mirror to see below, but that didn't work.

 

I still liked the plan where you don't have to take anything apart. It's good that you worked around it

 

I have the timing figured out. Here's what I did.

1) I removed the Vortech intercooler.

2) Then, I aligned the pulley red mark (not the white one) with the timing light mark (triangle) on the engine block. I simply turned over the engine with a 19MM wrench. It's a little difficult to see, but the following is a view of the mark.



Technically, if you think you can shoot a timing light and see the red mark, you can stop here. I had a hard time seeing the mark with any accuracy except with my head real close and turning the engine by hand (not going to put my head that close with the engine running), so....

3) With the OEM mark aligned I went ahead and placed a new mark on the pulley and engine. I recommend using an alternate color than the OEM (i.e. not red or white). I used a gold mark on the pulley and a black mark on the engine. The mark is not quite a perfect orientation, so I have to remember to keep my perspective the same when using the timing light (I'm just remembering to place the light in line with the radiator cover).



That's it, pretty straight forward. Now, in the morning just need to fit the timing light on the coil wires... and calibrate the AEM EMS following their instructions at a steady idle.
